The book is the third (practical) part of the Manual of First Aid. All texts are short, understandable, and always contain the right answer (marked with ?), which makes them suitable for self-study and testing the paramedics professional knowledge. In the first volume, the cases concern the following topics: airway and breathing assessment, proper interventions for patients with respiratory compromise, oxygen delivery systems, ventilatory support, respiratory anatomy and physiology, basic airway management, basic cardiopulmonary resuscitation, advanced interventions, cardiology, medical emergencies, traumatic injuries, gynaecology, obstetrics, and paediatrics. The last chapter deals with legal considerations, communication, scene safety and scene management, vehicle operations, hazardous materials, and mass casualty incidents. The second volume (revision lessons) is divided into twenty-four units, each of which contains about twenty casuistics on different topics.
